ionium

For the next two years, they continued to copublish on the atomic weights of uranium, thorium, and ionium. 86 In addition, their research showed that ionium was not a separate element but just an isotope of thorium.

An ionium collector, for which the radioactive material was kindly supplied by Mr.F. H. Glew, was used.

Other radioactive elements have been discovered since: actinium (Debierne), radiothorium and mesothorium (Hahn), ionium (Boltwood), etc.

Marie Curie - Nobel Lecture 1966

Taking the atomic weight of uranium as 238.5, the atomic weight of ionium should be 230.5, of radium 226.5, of the emanation 222.5, and so on.

Ernest Rutherford - Nobel Lecture 1966

For example, in the uranium-ionium-radium series, uranium expels two a-particles and each of the six following a-ray products one, i.e. eight in all.

Ernest Rutherford - Nobel Lecture 1966

I can only refer in passing here to the large amount of work done by various experimenters in analysing the long series of transformations of radium and thorium and actinium; the linking up of radium with uranium and the discovery by Boltwood of the long looked-for and elusive parent of radium, viz. ionium.

Ernest Rutherford - Nobel Lecture 1966

Thus were found the mesothorium now used by physicians and manufactured industrially, radio-thorium, ionium, protoactinium, radio-lead, and other substances.

Other radioactive elements have been discovered since: actinium (Debierne), radiothorium and mesothorium (Hahn), ionium (Boltwood), etc.
